The Budapest Card is the cheapest and easiest way to see Budapest. It includes unlimited public transport, reduced or free entry to museums, spas and sports facilities, as well as discounts at restaurants and city tours. You also receive a comprehensive booklet. Each Card is valid for one adult and one child up to 14 years of age. And at just 6,450 Ft for 48 hours and 7,950 Ft for 72 hours, it's a snip (a three-day tourist pass for public transport costs 3,100 Ft alone).
